American Airlines Alums?

Bruce Hicks is an authority on airline public relations having advised American Airlines on external and internal communications. Like Jack Keady, he has survived the acid test of working for American Airlines. What is it about A/A and their illustrious ex-workers?  Is A/A the finishing school of airline management producing marvels like Bruce Parker (CEO of the new US Airways)? Perhaps they just have a problem keeping so much talent with too few opportunities at the top.
